>                 Key: FELIX-6384
>                 URL: https://issues.apache.org/jira/browse/FELIX-6384
>             Project: Felix
>          Issue Type: Improvement
>          Components: Configuration Admin
>    Affects Versions: configadmin-interpolation-plugin-1.1.0
>            Reporter: Konrad Windszus
>            Priority: Major
>             Fix For: configadmin-interpolation-plugin-1.1.2
>
>
> Currently in https://github.com/apache/felix-dev/tree/master/configadmin-plugins/interpolation#default-values it is not stated that an empty value is not supported as default value. Still the following code is not replaced as expected
> {code}
> $[env:NON_EXISTING_VAR;default=]
> {code}
> This is due to the parsing logic in https://github.com/apache/felix-dev/blob/0aa232a4ff8f95e92d947027ac7d8010e2a0e142/configadmin-plugins/interpolation/src/main/java/org/apache/felix/configadmin/plugin/interpolation/Interpolator.java#L118 which detects the directive (in this case {{default}}) only in case there is at least one character after the {{=}}.
> This limitation should be lifted to also allow empty values as default values. At the same time values containing the character {{=}} should be allowed as well.
